Figure 1 shows the enclosing cabinet of the 35 apparatus which ispreferably of well finished sheet metal and is of rectangular formhaving a iiat top and sides. 'Ihe top and sides are preierablyindividually removable for access to the enclosed apparatus. The frontpanel has a door 40 i hinged at the bottom and opening outwardly whichis ilrmly heldin closed position by any suitable form of latching device2 at the top. 'Ihis door may be hinged at the side or top if desired. Inthe upper right hand corner of the iront panel is a manually rotatableindicator arm 3 adapted to pass over a dial 3a which is graduated toindicate the diilerent sequential operations as the arm 3 moves overitin a clockwise direction. This arm may be manually moved forwardly bythe 60 user in case it is desired to hasten any of the operations oromit any of them, the apparatus then continuing to functionautomatically from the new setting on. In the upper left hand corner ofthe iront panel is manually rotatable handle Ib for controlling thetemperature of the entering water as may be desired by the user througha three-way valve for regulating theintake from the hot or cold watersupply.

Referring to Figs. 2, 3 and 4, a fixed container 4 of cylindrical formis positioned so that its axis is horizontal and is fixed at one end tothe rear of the front panel' which is formed with rearwardly extendingsupports 4a and 4b for this purpose. The front end of the container 4 isprovided with a large central opening, as indicated in Fig. 4 oppositethe door I of the front panel.

n The rear end of the container 4 is closed and has wardly extendingarms lc and legs 5d which form supports from the base l of the machine.The container 4, at its lower part, has a downwardly extending formedportion 4c which is inclined downwardly toward the rear of the cabinetand is supported, at its lower portion, by a flange 5e extendingforwardly from a web 5f extending between the arms Bc of the supportingbracket. A drain pipe 1 enters the lowest end of the container 4 throughthe web If, as shown in Figs. 2 and 4.

Within the fixed container 4 is mounted a receiver 8 of cylindrical formand rotatable on a horizontal axis. It has a central circular opening8a` at the front end opposite the door I of the cabinet. The cylindricalportion is perforated by a series of closely placed small openings lbfor permitting the free passage of the liquid from the container 4 toand from the clothes within the receiver l. Mounted within thecylindrical portion of the receiver are axially extending baille plates8d for purposes of agitation during the washing, rinsing and finaldrying operations. lThese plates extend inwardly a short distance Withinthe receiver and are preferably three in number equally spaced apart.'I'he rear end of the receiver is entirely closed by the end portionthereof and is deflected inwardly, as shown in Fig. 4, and fixed to arotatable support 8c which is in turn keyed or otherwise fixed to arotatable shaft l. The support 5 not only forms a support for thestationary container 4 but also forms a bearing and support for `theshaft 9. The reduced end of the shaft 9 extends rearwardly through thebearing 5 and has fixed thereto the driving pulley 9b. This pulley isdriven by a belt 9a from the driving electric motor III mounted on thebase in the rear left hand corner of the machine, being shown at theright in Fig. 2.

On the base at the right hand side of the machine, as shown in Fig. 3,is mounted another electric motor II. On its rearwardly extending shaftand driven thereby is mounted the rotatable element of a centrifugalblower I2; and on a further rearward extension of the motor driven shaftis mounted the rotatable element of a centrifugal pump I3. On theforwardly extending shaft of the motor I I is mounted a driving elementserving to actuate the automatic sequence controlling devices containedwithin the control box I4.

'I'he water supply. is derived from two pipes I5 and I5a which extendthrough the rear plate of the cabinet and are connected, one to a hotwater house supply pipe and the other to a cold water house supply pipe.'I'he two pipes Il and Ilia enter a three-way valve I lb of any usualtype, from which extends a delivery pipe I5c across the rear of themachine at the top. From the valve I5b forwardly extends control shaftIIid to the front of the machine, as shown in Fig. 4, which is connectedat its front end to the water control handle 3b on the front panel ofthe machine in the upper left hand corner. Thus by turning the handleA3b the incoming supply of hot or cold water,'or both, may be regulatedby` means of the three-way valve to give any desired temperature of thewater entering the machine. In the water supply pipe lic. which crossesthe rear top portion of the machineHis inserted an automaticallycontrolled intake water valve I8, as shown in Fig. 2. This valve isnormally closed by spring pressure or gravity and automatically openedby exciting the coil of a solenoid magnet contained within the topportion IIia of the valve. 'I'his valve structure may be of any formwhich normally seeks the closed position and is opened only when itscontrolling coil is energized. The intake water supply pipe, afterpassing through the valve I8, extends forwardly and downwardly and isconnected at its front end to a hollow ring casting I1 which is formedon the rear of the front panel, as shown in Fig. 4, and is shown more indetail in Fig. 5. This ring casting I1 is concentric with the horizontalaxis of the machine and forms a circular entrance to the receiver 8 whenthe door is opened. The ring I1 is hollow, as shown in Fig. 4, and, asshown in Fig. 5, the hollow opening is partitioned into an upper andlower part by partitions` I 1a and I1b which are somewhat displaced fromthe horizontal for convenience Yof connection to the supply piping.'I'he lower divided portion of the ring serves as the intake anddistributor of the water or other cleaning liquid and is perforated atits lower central portion by a series of openings I1c which serve todeliver and spray the water through the opening 8a of the receiver on tothe clothes within it. These perforations I1c are likewise shown in Fig.4. Thus, when the water supply is on, the clothes are quite uniformlysprayed during the initial wetting for Washing and also during therinsing process. 'I'he ring I1 has an inclined outer surface, as shownin Fig. 4, and the inner side of the door I carries an inwardlyextending circular flange Ia which carries a circular gasket Ib which,when the door is closed, engages the inclined front face of the ring I1and serves to form a seal against leakage of the liquid. 'I'his gasketmay be of rubber or any suitable yieldable material.

The air supply for drying the clothes is taken from a continuouslyoperating air pump I2, as shown in Fig. 3, coming from an entrance pipeI 2a through an opening in the right hand side cover plate near the baseof the machine and, after passing through the pump, is forced through anoutlet pipe I2b, which extends across the lower portion of the machineand upwardly at the front portion and then into the upperpartitioned'half of the ring I1, as shown in Fig. 5. The air flow passesthrough this hollow ring and then out through an elongated opening I 2clocated at the lower part of the top portion of the ring I1 so as todeliver air downwardly toward the central opening 8a of the receiver, asshown in Fig. 4. An outlet for the air current is provided by a hole I2dat the right hand upper side portion of the container 4, as shown inFig. 3, from which hole the pipe |2e leads upwardly and out through ahole at the top of the right hand side plate of the cabinet.

'I'he drain pipe 1 from the container 4 passes through an automaticallycontrolled valve 1a, asshown in Fig. 2. This valve is spring pressed tonormally assume anopen position and. is automatically closed by asolenoid magnet contained within the topportion 1b of the valve. Thiselectromagnetic valve may be of any form which is adapted to close whenenergized and to open when de-energized. The drain pipe 1 continues fromthis valve and is connected to the intake of the,- continuously operatedpump |3. The outlet i3d-,of the pump, as shown in Figs. 2 and 3, passesout through an opening in the side plate of the cabinet at the lowerright hand corner and is connected to the waste drain of the household.

Mounted on one of the arms 5c of the supporting bracket, is a floatswitch I8, as shown in Figs. 2 and 3, in the form of a closed box from fthe bottom of which extends a pipe Ila which connects through an openingin the lower portion of the container 4 with the interior thereof. This-is so located that when the water level reaches a predetermined height,the float lib will rise and force upwardly a switch contact |8c andthereby interrupt-the circuit of the eletromagnetic valve I6 and permitthe closing thereof. Thus the supply of washing liquid can never riseabove this predetermined level, even though the control circuit ofthisvalve be controlled tending to open the valve at another controlcontact of the circuit.

The sequence control mechanism. contained within the control box |4 is,as shown in Fig. 6, driven by the shaft ||a of the control motor Withinthe box on the end of the shaft ||a is a worm I9 driving a worm wheelIsa, the shaft of which carries a worm |9b which in turn drives a wormwheel |9c having a shaft extending at right angles to the shaft of thewheel Ha. It will be understood that the shafts of this drivingmechanism are suitably supported in bearings in a manner understood bythose skilled in the art, these bearing supports being omitted from Fig.6 for the sake of clearness. The shaft of the wheel Isc in turn carriesa worm |9d which drives a worm wheel |9e as well as an upper worm wheelIsf, these driving wheels having parallel shafts at right angles to theshaft of the worm wheel |9d. The shaft of the wheel Ise carries a fixedeccentric or cam Ita which is adapted to intermittently engage anddepress a pin |9h. This pin is fixed at its lower end to a flexibleelement |81 which carries a contact |91 at its outer end and is fixedlysupported at its other end to support |9k. When the pin is not engagedby the cam |90, the contact Hi makes engagement with an upper fixedcontact |91 and when the pin |9h is depressed by the cam, it is causedto engage a fixed contact Ism mounted on the base of the control box. Itwill, of course, be understood that these engaging contacts areelectrically insulated from the rest of the apparatus and that theelement isi is mounted upon an insulating support and that the pin |9his likewise insulated from the ilexible element |91. Thus by this gearreduction, the eccentric |80 makes one revolution for a very largenumber of revolutions of the motor shaft lla; any suitable form of speedreduction mechanism may be used and the reduction proportioned to givethe desired ratio of revolutions of the driving shaft to that of theeccentric shaft.

On the opposite'side of the control box |4 from the shaft 'I la ismounted another shaft 2l 'shown in alignment with the shaft v| la. Theshaft 2l extends outwardly and carries at its outer end a bevel gear20a, as shown in Fig. 3, which in turn meshes with another bevel gear20h fixed on the lower end of an' upwardly extending vertical shaft 20c.This is suitably supported in bearings mounted on the inside of thefront panel and carries at its upper end another bevel gear 20d which inturn meshes with a bevel gear 20e on the inner end of a shaft passingthrough the front panel in the upper right hand corner thereof. On theouter end of this shaft is fixed the indicator arm I which indicates, byits movement with reference to the dial 3a. the successive stages ofoperation and the particular function being performed by the apparatusat any phase of lthe operating movement. The indicator 3 is controlledto make nearly one complete revolution during the entire series ofoperations.

Returning to Fig. 6, the shaft 20 extends inwardly through the controlbox and is connected by a one way acting clutch to another shaft 2|. Asuitable form of clutch is shown in Fig. 7, wherein balls or rollers 22are located in cut-away portions on the outside of the shaft 2| andenclosed byl a sleeve 20j' which is fixed to shaft 20. When the shaft 2|is turned in one direction, that is clockwise, in looking at Fig. 7,shaft 20 evident that when shaft 20 and its sleeve 20j Y is turnedindependently of movement of the shaft 2| in a clockwise direction, theshaft 2| will not be moved thereby. Thus the shaft 20 may be advanced bythe turning o f the indicator arm 3 to any position desired on the indexdial without turning the shaft 2 The shaft 2| has fixed to its inner enda worm gear 2lb which is driven by a worm 2|c on the shaft which carriesthe worm wheel Isf and which, as above pointed out, is driven by theworm Illd. Thus, in normal operation. the shaft 2| is driven by themotor shaft ||a at a great reduction in speed, this reduction being suchthat the shaft 2| is turned nearly one complete revolution during thecomplete sequence of the op- 1 erations of the machine.

The various operations are electrically controlled by means of asequence controller driven by the shaft 20. This consists of astationary insulating disc 23 mounted on the wall of the con trol box |4and concentric with the shaft 2|l.

The insulating block 2l carries a series of concentric contacts 23a, asshown in Fig. 8. Fixed to the shaft 20, but insulated therefrom, is acontact arm 24 which carries a series of contacts adapted to engagerespectively with the contacts 23a. The contacts carried by the arm 24should be individually springpressed against the contacts 23a so as toinsure proper engagement therewith as the arm 24 passes over them andany proper mounting of the movable contacts that will insure connectionof them with the contact arm 24 and proper engagement with contacts 23awhen the arm passes over them, may be utilized, as will be understood bythose skilled in the art. Likewise, instead of making the controller inthe form of a disc controller, it may be made in the form of a drumcontroller having the contacts 23a carried by a drum mounted on theshaft 20 and rotatable therewith while the engaging contacts of arm 24are fixed in posi- Cil tion, as will be understood by those skilled inthe art.

Referring to Fig. 8, the electrical connections of the various partsalready described are shown in their relations to the electriccontroller. The main driving motor i is shown in the lower right handcorner of the diagram and is indicated as a series type, or universalmotor having an armature with commutator connected in series with one orthe other of the reversible iield windings Illa and Ib, although anyform of reversible motor may be used and controlled to reverse itsdirection of rotation. The control motor II, which drives the air pumpI2 and water pump I3, as well as driving -the controller arm 24, islikewise shown as a series motor, although any suitable form of motormay be used which will give approximately constant speed, operatingcontinuously in one direction. The supply lines 25, 25' are shown at theleft of the diagram and pass through a main switch, such as a plug andreceptacle, for connecting the supply lines to the apparatus. Thereversing switch |91' is shown in the lower left hand corner of thediagram and is biased to have its contact |97' normally engage the upperiixed contact ISI. The eccentric ISU operates to intermittently depressthe switch I9i to engage the fixed contact Ism for reversing thedirection of rotation of the main driving motor I0, as will hereafter beexplained. The float valve I8 controlling the switch I8c is shownconnected in series with the winding of the electromagnet IGacontrolling the water supply valve I6. The winding of the electromagnet'Ib controlling the drain valve 'la is shown connected in series betweenthe supply line 25' and one of the fixed contacts of the controller. Aballast or load resistance 26 is shown connected in series with theswitch |91' and in turn is connected to contacts of the controller 23a.It serves to limit the maximum current to a predetermined amount whenthe motor I0 is reversed. A resistance 21 is connected in series withone of the field windings Illa and with the armature of the motor I0when the contact arm engages a contact of the controller to which theresistance 21 is connected. This resistance serves as a startingresistance for the main motor when it is to be operated in one directionat high speed and serves to gradually start the motor. When thisresistance is cut out of the motor circuit by the controller arm, themotor is brought to high speed. A heating resistance 28 is connected inseries between the supply line 25' and one ofthe contacts of thecontroller, this resistance being for the purpose of heating the airduring the drying operation of the machine and being located in the pathof the air as it emerges from the opening I2c as forced by the air pump,as indicated in Fig. 5.

In describing the operation, it may be first assumed that the contactarm 24 of the sequence switch or controller is inthe oiI position,making no contact with the iixed segments of the controller, asindicated in Fig. 8. The indicator arm 3 is then in the verticalposition shown in Fig. 1. The door of the front panel is opened and thetextiles to be washed are inserted through the opening 8a and placed inthe receiver 8, A proper amount of powdered or flaked soap or similarwashing material, is thrown over the dry textiles after their insertion.The door I of the front panel is then closed. 'I'he operator then turnsthe indicator arm 3 to the right for initiating the operation of theapparatus which then continues to pass through the different operationsin se-` quence, as automatically carried out by the control devices. Theturning of the dial indicator 3 slightly to the right causes. throughAthe bevel gears and shaft c, the turning of the shaft 2U. This resultsin the contact arm 24 being moved manually in a clockwise direction tomake contact with the strip A of the controller. The contact arm 24 iselectrically connected to the supply line 25 and the engagement withcontact A closes a circuit to start the control motor II as follows:from the arm 24 to contact A and thence to the motor Il and then to thesupply line 25'. This starts the control motor which operatescontinuously during the entire cycle of movements because the contactstrip A is continuous and is the last contact broken when the arm 24passes off this contact strip, as evident from the controller diagram.As soon as the motor Il starts, it serves, through the reduction gearalready described, to drive the shaft 2 I and thereby slowly tofmove thecontact arm 24 over the flxed contacts of the controller. The controlmotor Il also serves, during its operation, to drive the drain pump I3and the air pump I2, insuring the quick emptying of the container 4 atany time the drain valve 'la is open and also serving to pass acontinuous flow of air through the receiver, as already described, whichbecomes effectively utilized in the drying operation. The travel of thecontact arm 24 brings the same into engagement with the contact strip B.This closes a circuit through the main driving motor I0 and starts thesame in one direction by means of a circuit from the contact arm 24through the contact strip B, thence through the load resistance 26 toswitch I9i to the upper contact I 91 and then through the field windinglua and armature I0 of the motor to the other side of the line. In themeantime, the eccentric ISg of the control box is driven by the motor Ilthrough the reduction gearing, already described, so that itcontinuously operates iirst to force the switch I9 against the contactIsm and then to permit the switch to engage the contact |91 and then tocause it to engage the contact Ism alternately to cause the reversal ofthe motor I0, as is evident by tracing the circuits. Thus, when thecontact, ISm is engaged, the current passes from the arm 24 throughcontact B, load resistance 26, switch |91', contact ISm andthencethrough the field winding Illb and motor armature to the otherside of the line. This reverses the iield of the motor 4and causes itsrotation in an opposite direction from that occurring when the eldwinding Illa is energized. 'Ihe reversal of the motor I0 serves, throughthe driving belt 9a and pulley 9, to reverse the direction of rotationof the receiver 8 for the washing operation. The time of rotation of theeccentric lag may be made any interval desired but it is preferablygeared so that the receiver 8 is turned about one revolution or somewhatmore in each direction before reversal.

In addition to engaging the contact B, the arm 24 likewise engages thecontact C. I'his closes a circuit from the line 25 through the arm 24,contact C and winding of the magnet of lb to the other side of the line.This automatically closes the drain valve 1a. Contact is also made bythe arm 24 with the strip D of the controller which closes a circuitfrom one side of the line, through the oat switch lic and then throughthe winding of the magnet lia to the other side of the line. 'I'hisautomatically opens the water supply pipe and permits the entrance ofthe ywashing liquid through the spray holes I1c, the operator havingadjusted the handle Ib on the front panel of the cabinet to give adesired temperature of the entering water from the hot or cold watersupply by means of the three-way valve lib. The water continues to risein the container 4 to a predetermined level at which time the floatvalve opens the switch llc and breaks the circuit of the electromagnetof supply valve I6 and permits the same to assume its closed position.

The washing action continues under these conditions for a predeterminedtime while'the arm 24 is slowly travelling over, and in contact with,the four contact strips A, B, C and D. After the washing action hascontinued a suflicient time to thoroughly wash the textiles,` the armpasses off the contact strip C which de-energizes the drain valve andpermits it to open and, through the action of the pump Il, the usedliquid is rapidly drained from the container 4. The draining of theliquid causes the float valve llc to close which energizes the circuitof the electromagnet of supply valve I8 and results in a supply of freshwater being sprayed within the receiver through the perforations I1c. Inthe meantime, while the arm 24 is continuing to travel over the contactsA, B and D, the receiver 8 is being continuously reclprocated andtumbling the textiles therein by the action of the bales 8d and thecontinued reversing action. Thus, during this rinsing process,` acontinuous supply of fresh rinsing water is sprayed upon the textileswhile they are variously tumbled and the container 4 is kept empty bythe continued action of the pump I2, Thus a thorough and eifectiverinsing of the textiles takes place.

The rinsing period occurs while the contact arm 24 is travelling fromthe end of the contact strip C to the ends of the contact strips B andD.

When the arm 24 passes off the contacts B and D, the circuit of the mainmotor III is interrupted and it temporarily ceases to operate and thecircuit of the electromagnetic inlet valve is likewise opened permittingthis valve to close. The next operation is to extract the surplus waterfrom the textiles by rotating the receiver 8 at high speed in onedirection. In accomplishing this result it is vitally important that thetextiles be quite evenly distributed circumferentially around the insideof the receiver 8 so that the load producing strain on the receiver 8 isproperly balanced. Otherwise the unbalancing will cause a great sidestrain on the machine. especially at the high speeds, resulting in apounding and racking effect which might lead to serious damage. It is,therefore, important in the automatic control of the receiver 8 toattain the automatic even distribution of the textiles within thereceiver before high speed operation is arrived at. This is accomplishedby bringing the speed of the receiver gradually up to high speed. Duringthis gradual increase in speed the 'textiles whichare initially at thebottom of the receiver 8 are gradually carried around and tumbled by thebaflles 8d until, as the speed increases, the textiles are gradually andevenly distributed around the interior of the receiver 8 so that, whenpassing to high speed, no unbalanclng exists and the machine operatessmoothly at the highest speed for centrifugally extracting the water.

Thus, referring to Fig. 8, the arm 24, after the completion of thewashing and rinsing process, next engages the contact E. This closes thecircuit of the main motor II! from the supply line 28 through arm 24,contact E, resistance 21, field winding Ila and armature I0 to the line25'. The resistance 21 may be adjusted to give the desired rate ofacceleration in speed and, after this has once been determined, theresistance may be nxed. The motor I0 being now operated in one directioncontinuously and under a much less load than during the washingoperation, gradually increases in speed while the arm 24 is passing overthe contact E. It then engages the contact F which results inshortcircuiting the resistance 21 in the circuit of the motor andpermits the motor and receiver 8 to pass to high speed operation forextracting the water. When the arm 24 engages the contact F, it likewiseengages the contact G which is electrically connected to contact D andserves to energize the inlet valve for the purpose of a short intervalof final rinsing with fresh water. The arm 24 then passes oil. thecontact G while continuing engagement with the contact F for operatingthe main motor and receiver 8 at high speed for extracting the maximumamount of water centrifugally. Thiscompletes the extracting operation.

. The contact arm next passes off the contact F for stopping the motor,and after a sumcient time interval permitting the receiver to come torest, it then engages the contact H to again start the motor. 'Ihiscloses the circuit of the main motor I8 through'the load resistance 28and reversing switch |91 and thus causes the motor III and receiver 8 tostart and resume the reverse action, the same as took place during thewashing operation as previously described. The damp clothes are nowtumbled in the receiver 8 by this reverse operation and the continuousair flow through the receiver, as forced by the v air pump I2, gives aneffective and quick drying operation. The drying is hastened by theelectric heater 28 which becomes energized by the arm 24 engaging thecontact strip K by a circuit from the arm 24 through contact strip K,heating resistance 28 and thence to the other side of the supply line.The heated air flow soon completes the dryingof the clothes during thepassage of the arm 24 over the contact strips H and K, after which themain motor and heating resistance circuits are broken by the arm 24passing of! these contact strips. Soon afterward the arm 24 passes offthe contact stripl A and the circuit of motor II is interrupted and thecycle of operations is then completed.

The user then opens the door I of the front panel and removes the drytextiles. Thus the soiled textiles or fabrics are introduced into themachine dry, are subjected to a thorough washing, rinsing, extractingand drying operation in sequence and at the completion of the cycle, thetextiles vare removed from the machine clean and dry.

If, at any time the user desires to hasten any one of the sequentialoperations, or to pass over them quickly, the operator may turn theindicator arm 3 in a clockwise directionr to any part of the dial andthen let the machine continue the automatic'operation from that point onor until again hastened by the user. In this manual turning of theindicator arm 3, the shaft 2li is turned, as already explained, togetherwith the contact arm 24, the one way clutch, already described,permittingthis manual forward adjustment. After such adjustment thecontrol motor II takes up the continued movement of the arm 24 asalready described.

It is thus apparent that by this improvement, the machine serves toeffectively carry out the washing, rinsing, distributing, extracting anddrying operations all within a single container and receiver in anautomatically controlled series of operations without the use of anyauxiliary compartments, tanks or supplementary apparatus. It isconveniently accessible through the front panel door on the front sideof the machine for introduction and withdrawal of the fabrics and avoidsthe necessity of any intermediate handling, splashing or dripping ofwater or of the washing liquid. It likewise, by its simplicity andutilization of one container and receiver for all purposes, permits `theunit to be made of a comparatively small size adapted for use in smallapartments while being of ample capacity. 'I'he unit is obviouslycapable of being made in different sizes for fullling the requirementsof the larger households.

It is evident that the duration of the different periods of the cyclemay be changed by lengthening or shortening the contact strips of theelectric controller and, if desired, one or more of the sequentialoperations may be omitted without departing from the scope of theinvention, and various changes may obviously be made in the structureand relationship of the various parts of the apparatus.

In case it be desired to soak the fabrics in the machine =beforewashing, the apparatus could be started in the usual way and thenstopped at the initiation of the washing period, as by pulling vout theplug connection to the house wiring, or otherwise opening the maincircuit. In such a case if the house drain is above the drain outlet ofthe machine, the stopping'of the drain pump would avoid emptying thecontainer; and if the house drain is below the drain outlet of themachine, a shut oil' valve in the drain connection could be manuallyclosed. The soaking could also be accomplished without starting themachine by providing a by-pass having a manual valve, around theautomatic valve I6 for filling with washing liquid. Likewise, in caseonly a comparatively short period of soaking were desired, thecontroller 23a could be modified by delaying the starting of the motorI0 for permitting a soaking period while the arm 24 slowly traverses thestrips A, C and D for some distance before engaging the strip B. Thiscould obviously be accomplished by extending the strips A, C and D somedistance in a counterclockwise direction, with reference to Fig. 8,beyond the lower end of strip B which controls the motor i0. y

Also although an air .blower I2 has been described for maintaining acirculation of air through the. receiver 8 for drying the fabrics, thisair blower may be -omitted in some instances.

container for drying may be obtained. The,

bailies Id serve to assist the airflowand special fan blades could be.attached to the receiver lf- I I desired.

Althoughl in the above described machine the receiver I is `drivenvalternately in opposite di- A sufficient passageA of air through thereceiver 3 for drying may be obtained by the re-v ceiver l itself actingas a blower because it acts rections during the washing and dryingperiods,

the control could readily be modified to drive the receiver 8 in onedirection only at a comparatively slow speed during either one or bothoi these periods and still obtain satisfactory washing and dryingoperations. In that case the reversing switch I9i would be unnecessaryand the circuit of motor i0 would then pass from contact strips B or H.or both strips, through a suitable resistance such as 26 for maintaininga low speed and then through the motor to the other side of the line, asshown in Figs. 17 and 18. In such a slow speed movement of the receiver8 in one direction only, the fabrics are carried along by the baiilesand then fall or tumble as they approach or arrive at the inside top ofthe receiver, during either the washing or drying period or both, asdesired.

In the remaining figures of the drawings another embodiment of theinvention is shown wherein only one electric motor is used whichoperates continuously in onedirection and wherein the time control ofthe different operations is dependent upon aclock mechanism as anotherembodiment of the invention, instead of using a control motor with areduction gear, for this purpose. Likewise, in this further embodimentof thoe invention, instead of reversing the main motor, a reversing gearis utilized for obtaining the reverse action during the washingoperation and during the drying operation.

Thus referring to Figs. 9, 10 and 14, the parts having the samereference characters as already referred to, are similar to thosealready described. The single driving electric motor 30 is mounted onthe base at the rear of the machine and has its axis parallel with thefront panel of the cabinet. The shaft of this motor drives the main pumpI3 mounted at one side of the motor and the air pump i2 mounted at theother side of the motor. The bottom of the container 4 is convergedtowards the middle, as indicated in Fig. 9, and the drain connection isconnected thereto at its lowest point and passes through theelectromagnetically controlled drain valve la, normally open, and thenceto the pump I3 which delivers to the waste system of the household. Theair pump i2 has its inlet through a hole in the rear of the cabinet andan outlet, which is connected by the pipe IZb, preferably of copper andbendable, to the upper half section of the ring I1, the same asdescribed in the former apparatus. The water supply is likewise the sameas already described, the supply pipe IBc having located therein theelectromagnetically controlled valve I6, normally closed, and the outletend of the pipe |-5c`is connected to the lower part of the casting I -1as previously described. As thus far described, the structure isgenerally similar to that disclosed by Figs. 1 to 8 and similarcorresponding parts need not be again. particularly described.

The gear drive for controlling the rotation of the receiver 8 is, asshown in Figs. '9 and 10, enclosed within a box 3| mounted at theA rearof the machine and is supported bythe bracket which likewise serves lasthe bearing support for the shaft driving the receiver 8 and which alsoserves to support the rear end of the container '4. The horizontal shaft32 has an end projectaston theshaft or the motor 3o.

Referring to Figs. 11 to 13, the shaft 32 is shown mounted in bearingsdepending from the top of the gear case and has i'ixed to it a worm 32a.This worm continuously drives' in one direction the worm wheel 34supported by a stub i shaft mounted from the inner front side of thegear case. Pivotally supported. on a stub shaft at the bottom of thegear case extending'from- 82 is fixed a bevel gear 32h. The shaft lwhich drives the rotatable receiver 8 of the machine is, as shown inFig. 13, provided with an extension l 9c which enters the gear box andis supported in opposite sides thereof. 'I'he axis of this shaft is inthe horizontal plane of the axis of the driving shaft 32 and carries adouble bevel gear 31a and 81h. This double bevel gear is slldably keyedto the shaft 8c and may be moved to cause the bevel portion 31a toengage the bevel gear 32h. or may be moved to cause the bevel gearportion 81h to engage the segmental bevel gear 35. The double bevel gearhas a central circular slot 31c. This slot is engaged by the forks of ashifting element 38 which is pivotally mounted above the gear in anupwardly extending portion of the top of the gear case, as shown in Fig.12. 0n the top of the gear case is mounted a solenoid magnet having awinding 33 and a plunger 38a. the axis of which is horizontal. The outerend of the plunger is above the shifter 38, the latter being plvotallyconnected thereto by a pin and slot connection. A tension spring 39h issecured 40 at one end of the enclosing box 3lc of the magnet and at itsother end to the end of the plunger 38a. The spring thus tends to movethe plunger and shifter 38 so that normally the bevel gear portion 31ais in engagement with the gear 32h.

In this modification of the invention instead of using an electric motordriven electric controller as in the embodiment first described, theactuator for the controller is independently driven by -a clock'mechanism. This driving means may .be of any suitable form, such as theusual spring wound clock mechanism with the usual escapement and forpresent purposes the same should be geared so as to drive the actuatedshaft about one revolution during a period of 30 or 40 minutes, which isassumed to be the time necessary for passing through the complete cycleof operations. In Figs. 15 and 16 the clock mechanism is indicatedgenerally by the closed casing 48 from 00 the face of which projects thedriven clock mechanism shaft 40a and also below the same projects ashaft 40h which is the shaft for winding the clock' mechanism. Slidablymounted on the outer end of the shaft 40a and driven thereby is oneelement 4l of a disk clutch. The other element 4ia o f this clutch issecured to a shaft 4ib mounted in the enclosing casing 42. The outer endof the shaft 4Ib is enlarged outside of the casing and has a squarecentral hole 4ic in its outer end. The control indicator arm 3 mountedin the upper right hand corner in the front panel of the cabinet, -asshown in Fig. 1, is in the present case secured to a shaft 43 whichpasses through the panel. The inner end 43a of this shaft is squared toslidably engage the hole 4Ic. The shaft 43 is slidably mounted in thefront panel so that it may be pushed inwardly by the user, a compressionspring 43h normally tending to hold the shaft 43 outwardly so that,although still having a driving engagement with 5 the shaft 4Ib, it isnot normally pushed in the full distance within the hole lic. Mountedupon the inside face of the front panel in a fixed position is aninsulating disk 44, the inner face of which carries the concentriccontact strips 10 of the controller. 'Ihe shaft 43 is freely movablethrough the center of this longitudinally. 'Ihe shaft 43 drives thevinsulated contact arm 45 which engages through yieldable movablecontacts, the contact strips on the face of the disk 44. 15

A pin 43 'is freely movable longitudinally through a central hole in theshaft 4Ib and likewise freely movable through the clutch element 4|a andengages, at its inner end the center of the clutch element 4I. The otherend of the 2 pin is extended to engage the inner end of the squaredportion of the shaft 4ia. Around the driving shaft 48a of the clockmechanismis a compression spring 48e which forces the clutch element 4Iinto engagement with the clutch ele- 25 ment v4|a under normal operatingconditions.

The clock mechanism is manually wound by the operator by turning theindicator arm 3 in a ccunterclockwise direction which is reverse to thedirection of travel of the arm s dunne a operating conditions. For thispurpose a curved arm 41 is fixed to the winding shaft 40h of the clockmechanism and is engaged at its outer end by an arm 48 nxed to the shaft4Ib. It is evidem from Fig. 1s. that when the arm 4s is 35 turned in acounterclockwlse direction, it will turn the arm 41 and its shaft 48h ina clockwise direction and so wind the spring of the clock suflicientlyto operate the same an hour or more. The arm 48 is made in two parts, asindicated 40 in Fig. 16, one part being plvotaliy mounted on the outerend of the inner part so that in case the arm 41 is in the path of themovement of the arm 48, when the latter is turned in a clock- -wisedirection, the pivoted end of the 'arm 48 45 will pass over the arm 41.When the arm 48 is moved in a counterclockwlse direction, the outerpivoted end of the arm 48 is prevented from rotation on its pivot in theopposite direction and, therefore, is capable of forcing the arm 50 41in a direction to wind the clock. It will be understood that the windingshaft 40h of the clock is driven in a counterclockwlse direction as theclock unwinds, `and a pin 41a ilxed on the outer casing of the clocklimits the movement 55 of the arm 41 in a counterclockwlse direction.Fixed to the insulating disk 44 is a segment 49 which overhangs certaincontacts of the controller, as shown in Fig. 15. This segment permitsthe contact arm 48 to pass freely under it 60 when normally driven andserves as a protector for insuring proper operation of the contact arm45 when manually moved by the operator. Thus whenever the operatorwishes to turn the dial indicator arm 3 manually, to reverse the same 65for winding the clock mechanism, or to advance the same during normaloperation of the machine, in order to selectively hasten some of theoperations, the arm 3 must be pushed inwardly as it cannot be turnedagainst the clock mecha- 70 nism. When thus pushed in, the pin 46 ismoved inwardly and forces the clutch member `4I away from the clutchmember 4Ia against the pressure of the spring 40e. This releases theclock mechanism from the shaft lib and permits the 75 operator freely toturn the same in a counterclockwise direction for starting the automaticoperation, or to turn the shaft in a clockwise direction to hasten thenormal operations when desired. During this movement the arm can freelypass over the outside of the protective segment 49 but cannot bepermitted to engage any of the segments under this shield when releasedby the operator because the shield will then hold the arm 45 from cominginto contact with the contact strips on the insulating disk 44. Byfurther turning the arm 3 and contact arm 45, the operator may move thesame past the shield 49 and permit it to engage segments at any otherportion of the controller.

The control of the various parts of this form of the invention and -theautomatic action thereof will be understood by reference to Fig. 14wherein parts already described are similarly designated. Fig. 14 showsthe parts in their inoperative condition. The arm 45 is then inengagement with a pin 45a where it has been forced by the clock incompletion of the sequential operations of fthe machine. After theoperator has inserted the textiles within the receiver 8 and sprinkledthe same with the washing substance, such as powdered or fiaked soap,the dial arm 3 will be pushed inwardly and turned counterclockw'isewhich will push the pin 46 inwardly and unlatch the clutch from theclock mechani-sm and cause the winding of fthe clock and bring the arm45 to engage the other side of the pin 45a. 'I'he arm 3 is then releasedand the closing of the clutch will permit the clock to start driving thecontact arm 45 in a clockwise direction. The contact strips of the fixedportion of the controller are represented in Fig. 14 and also in Fig. 8as viewed from the front of the machine for simplicity of understanding.As the arm 45 moves from the pin 45a in a clockwise direction, it firstengages the three inner concentric contact strips L, M and N. Theengagement with the strip M closes the circuit from the line 25 throughthe arm 45 to the strip M and thence through the winding of theelectromagnetic drain valve Ito the other side of the line. This closesthe drain valve. The engagement with the contact strip L closes thecircuit across the line through the winding 39 of the gear controllingmagnet and forces the portion 31h of the bevel gear into engagement withthe segmental gear 35. The engagement with the contact N closes acircuit across the line through the float switch I 8c and the winding ofthe water supply valve I6 to permit the spraying of the incoming waterover the textiles in the receiver 8. The opening of this circuit by thefloat switch, at a predetermined level of the washing liquid, willpermit the automatic closure of the water supply valve. The engagementof the contact arm 45 with the outer contact strip O closes a circuitfrom one side of the line through the strip O to the field winding andamature of the motor 3U and to the other side of the line. This startsthe electric driving motor 30 which drives the shaft 32 of the gear boxand by means of the worm and wheel drive and link 36 causes areciprocating movement of the segmental gear 35. The gear ratio is suchthat the receiver 8 will be alternately driven in opposite directionsthrough the segmental gear 35 about one revolution or somewhat more ineach direction. This reversing washing action continues while thecontact arm 45 continues to travel in a. clockwise direction over thecontact strips L, M, N

and O. After a suitable washing period, the arm 4l passes of! the stripM, at which time the circuit of the winding of the drain valve 'la isbroken, permitting the same to open and allowlng the -drain pump toforce the waste water out of the machine.

The lowering of the liquid level in the container 4 soon permits theclosure of the float switch I8c which causes the energizwtion of thewinding of the inlet valve to admit a supply of fresh water. Thus, whilethe receiver l is continuing to be reversed by the driving gear andtumbling the textiles, the water is sprayed within the receiver to givean effective rinsing of the textiles while the contact arm continues topass over the contact strips L, N and O. It then passes off the strip Owhich breaks the circuit of the motor 30 and stops the driving of therel ceiver 8. The arm next passes off the contact strip N and breaks thecircuit of the winding of the inlet valve permitting it to close; and itlikewise passes off the strip L and breaks the circuit of the winding39, permitting the spring 39h to draw the plunger 39a to its initialposition and thereby shift the bevel gear portion 31a into engagementwith the bevel gear B2b. This completes the rinsing operation. 'I'hecontroller is now in a position to initiate the extraction of the waterfrom the textiles by high speed centrifugal action and in passing tothis operation, the receiver 8 must be gradually increased in speed soas to permit the even distribution of the textiles within the receiver 8to give a proper balancing thereof before passing into the high speedoperation of the receiver in one direction of rotation.

For this extracting operation, the arm first engages contact strip Pwhich closes the motor circuit from one side of the line through theresistance and thence through the motor to the other side of the line.'I'his resistance serves to start the motor at slow speed and to give acomparatively slow rotation of the receiver 8 in one direction, thebevel gears 31a and '32h being now in engagement for this purpose. Thecontinued movement of the contact arm 5 causes it to next engage thecontact Q which results in somewhat increasing the speed of the motor bycutting out a portion of the starting resistance 50. Further movement ofthe contact -arm results in cutting out another section of thisresistance by engagement with the contact strip R. In next engaging thecontact strip S, all of the resistance 50 is removed from the circuit ofthe motor which results inthe receiver 8 being driven at a high speedfor centrifugally forcing the water from the textiles. This high speedaction continues while the contact arm 45 traverses the strip S. Duringthe gradual increase in speed of the receiver 8 and before attaininghigh speed, the textiles will be evenly distributed around the inside ofthe receiver l as the starting resistance is gradually cut out, thuspreventing the possible damaging results -and objectionable operationwhich would accompany high speed operation if the load were unbalanced.Although the resistance 50 is divided into 3 sections, this number maybe made more or less depending upon the maximum speed of the machine andother factors of design.v Thus, in Fig. 8, only one step of a startingresistance is utilized.

In Fig. 14 the dotted lines enclosing the contact strips Q, R and Sindicate the shield 49 previously described in connection with Fig. 15-

-This shield, as already explained, permits the contact arm 45 to passunder the same during the normal sequential operation of the apparatus,but when the operator attempts to turn the indicator arm 3, afterpushing it inwardly, the shield will not permit the operator to causethe manual engagement of the contact arm 45 with the strips Q, R and Sbecause the arm 45 must be turned beyond the two limits of the shield49, in one direction or the other, before the contact arm 45 ispermitted to engage any of the contact strips. If the operator wishes tohasten or pass over any of the operations of the machine otherwiseautomatically controlled, the indicator arm 3 may be pushed inwardly andadvanced during the normal operation of the machine, to any position.and from there continued, but the shield 49 requires the automaticcontrol and proper inclusion of the sections of the resistance 50 in themotor circuit during the gradual increase in speed and equalization ofthe load when passing to the high' speed extracting operation.

After completion of the extraction process, by the contact arm passingoff the strip S for stopping the motor 30, and after'permitting asumcient time interval for the receiver 8 to come to rest, the contactarm 45 next engages the contact strip T. This excites the solenoidmagnet winding 89 which shifts the double bevel gear so that the portion31h is moved into engagement with the segmental gear 35. The contactstrip U is next engaged by the contact arm which closes the circuit ofthe electric motor which thereby causes the driving of the receiver 8 ina forward and backward rotation alternately, as already explained withreference to the washing action. The circuit of the heating resistance28 is also closed at this time by the contact arm engaging the strip V.Thus during the tumbling of the textiles by the forward and backwardmotion of the receiver 8, the air flow through the receiver, as forcedby the pump I2, is caused to pass around the heating resistance 28giving a warm ow of air through the receiver. Thus the textiles aredried while the contact arm 45 slowly travels over the length of thestrips T, U and V. The cycle of operations is completed by the contactarm 45 passing from the ends of the strips U and V, which stops themotor and breaks the circuit through the heating resistance and thenpassing of! the strip T, which opens the circuit of the winding 3S andpermits the double gear to be shifted to its normal position by spring39h into engagement with the bevel gear 32h. The arm 45 then continuesits travel, as propelled by the clock mechanism, until it engages thepin 45a, as shown in Fig. 14 The user may then remove the textiles fromthe receiver 8 after having been washed, rinsed, water extractedtherefrom and dried, as automatically controlled and carried out inproper sequence with the duration of each operation designed to give themost effective results. If, at any time, the user wishes to hasten anyof these operations, the indicator arm 3 is pushed inwardly and turnedin a clockwise direction to any amount desired and then released, atwhich time the automatic operation will resume 4its control and continuefrom that point on, the protective shield 49 preventing, however, anymanual control of the contact arm 45 in its successive engagement withthe contact strips Q, R and S for the reasons already explained.

Although preferred embodiments of this invention have been described, itwill be understood that various modifications may be made withoutdeparting from the scope thereof.
